Photopolymerization offers spatial resolution, low energy consumption, and high curing speeds, making it a widely used technology in additive manufacturing. The kinetics of the physical transformation of the resin from liquid to solid (cross-linked) state induced by photopolymerization and the kinetics of the solid-liquid interface formation of resin multilayer are the key to achieving controllable high-precision manufacturing. By modulating precursor resin components and combining grazing incidence small angle X-ray scattering (GISAXS), the UV-curing induced nanostructure and the buried interface of resin multilayer are probed. We reveal how solvents and additive monomers determine in nanostructure and multilayer interface formation during photopolymerization.
